Many thanks, for your kind comments. After sending my query to the list, I have made a copy of my installation into another partition, and redid the installation. As it stands, I have /dev/sda1 with 12.2 without YOU, and /dev/sda2 with YOU. The console is working okay as usual, and I can log on as root, or another user account in kde or gnome. I did try to look into dual-booting in the hope of starting up sda2, but have to admit falling behind on Opensuse. Under 12.1 and 11.x, there is a simple script /boot/grub/menu.lst, that I can manually add in a second boot entry. But this file is no longer present, so cannot reboot the YOU applied version to try out your suggestions, sorry... I have however got a copy of the Xorg.0.log, that I have attached here. In comparison from the non-YOU patched version, I can see the patched version is trying to use the module sis [ 1984.582] (II) LoadModule: "sis" [ 1984.582] (II) Loading /usr/lib64/xorg/modules/drivers/sis_drv.so [ 1984.583] (II) Module sis: vendor="X.Org Foundation" [ 1984.583] compiled for 1.12.3, module version = 0.10.4 [ 1984.583] Module class: X.Org Video Driver [ 1984.583] ABI class: X.Org Video Driver, version 12.0 [ 1984.583] (II) SIS: driver for SiS chipsets: SIS5597/5598, SIS530/620, SIS6326/AGP/DVD, SIS300/305, SIS630/730, SIS540, SIS315, SIS315H, SIS315PRO/E, SIS550, SIS650/M650/651/740, SIS330(Xabre), SIS660/[M]661[F|M]X/[M]670/[M]741[GX]/[M]760[GX]/[M]761[GX]/[M]770[GX], SIS340 [ 1984.583] (II) SIS: driver for XGI chipsets: Volari Z7 (XG20), Volari V3XT/V5/V8/Duo (XG40) [ 1984.583] (--) using VT number 8 [ 1984.615] (WW) Falling back to old probe method for sis [ 1984.615] (EE) No devices detected.

I have mounted OpenSuse 12.2 on a DELL Optiplx 960 from scratch.
After the installation, all seems to be working fine.
I then applied YOU to update all components, and rebooted. The system starts up to the point that says starting up ramdisk, the console screen then goes blank (black).
I can log on over the network afterwards.
The Xorg.log says: x server for display 0 cannot be started - session disabled.
No screen is specified.
Looks like the console start up screen is somehow corrupted.
There is no /etc/X11/xorg.conf, but a set of /etc/X11/xorg.conf.d/ files. A new scheme that I am not familiar with now.
Those files are nothing but xorg.conf separated into separate sections. Some are optional, and if you look inside them you'll see the video related ones are nothing but comments. They're useful to uncomment if one needs to override automagic configuration, e.g. to force a specific non-native resolution, enable panning, or to force DPI. You might want to try renaming the directory temporarily before a boot to see if it changes your problem.
Does anyone have any idea what happens?
No, but I'm going to guess it's Plymouth related. None of my older Optiplexes have done this. Try adding noplymouth & splash=verbose to the cmdline, and remove quiet, before booting to see if there are any clues in the startup messages. Does booting using the failsafe stanza help at all? The failsafe stanza adds nomodeset, which prevents use of the Intel driver, so it's only a workaround for diagnostic purposes. Without doing failsafe boot, can you show us Xorg.0.log via susepaste.org, and output from 'lspci | grep VGA' and 'cat /proc/cmdline'? If using a DVI cable, can you try switching to a VGA cable, or vice versa, just to see if it changes anything? Check http://en.opensuse.org/SDB:Configuring_graphics_cards to see if anything looks helpful. Also try from cmdline 'zypper ref; zypper up' to see if maybe you got a mix of older and fresh updates that are incompatible in some way and missed by YOU. -- "The wise are known for their understanding, and pleasant words are persuasive."
